2048 is an annoyingly addictive game. The concept is simple: join the numbers and get to the 2048 tile. You use the arrow keys to move the tiles, and when two tiles with the same number touch, they merge into one. 2 and 2 become 4, 4 and 4 become 8, 8 and 8 become 16, and so on.

Simple concept, yet incredibly hard to do! My current high score is 4552, with a 512 tile being the highest numbered tile I’ve reached.
